electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. From 3.0.6 to 3.8.8, This vulnerability is fixed in 3.9.0.
Broadcast events allow malicious software to rewrite the device's default Mobile Device Management (MDM) endpoint address, shifting administrative ownership to an external attacker.
Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In versions prior to 3.27.0, an issue in Kata with Cloud Hypervisor allows a user of the container to modify the file system used by the Guest micro VM ultimately achieving arbitrary code execution as root in said VM. The current understanding is this doesn’t impact the security of the Host or of other containers / VMs running on that Host (note that arm64 QEMU lacks NVDIMM read-only support: It is believed that until the upstream QEMU gains this capability, a guest write could reach the image file). Version 3.27.0 patches the issue.
Cilium is a networking, observability, and security solution. Prior to 1.17.14, 1.18.8, and 1.19.2, when Cilium L7 functionality is enabled, the embedded or standalone Envoy instance creates a world-accessible admin.sock on cluster nodes, allowing a local attacker to access Envoy admin endpoints, expose TLS secrets, disrupt cluster traffic, or terminate Envoy. This issue is fixed in versions 1.17.14, 1.18.8, and 1.19.2.
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.61.1, a broken access control vulnerability in the TUS protocol DELETE endpoint allows authenticated users with only Create permission to delete arbitrary files and directories within their scope, bypassing the intended Delete permission restriction. Any multi-user deployment where administrators explicitly restrict file deletion for certain users is affected. This issue has been patched in version 2.61.1.
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 3.9.0 and prior to version 4.14.3, a privilege escalation vulnerability exists in the Wazuh Manager's cluster synchronization protocol. The `wazuh-clusterd` service allows authenticated nodes to write arbitrary files to the manager’s file system with the permissions of the `wazuh` system user. Due to insecure default permissions, the `wazuh` user has write access to the manager's main configuration file (`/var/ossec/etc/ossec.conf`). By leveraging the cluster protocol to overwrite `ossec.conf`, an attacker can inject a malicious `<localfile>` command block. The `wazuh-logcollector` service, which runs as root, parses this configuration and executes the injected command. This chain allows an attacker with cluster credentials to gain full Root Remote Code Execution, violating the principle of least privilege and bypassing the intended security model. Version 4.14.3 fixes the issue.
